Intracoronary ultrasound observations during stent implantation.
T he Palmaz-Schatz stent has been used successfully to improve primary angioplasty results, to treat large coronary dissections, or to prevent impending closure of the lumen.-1-5 The determination of successful stent implantation is based on the angiographic appearance. However, angiographic projection imaging may not reveal the three-dimensional geometry that is necessary to appreciate full ex...
متن کامل[Multicenter study of intracoronary stent implantation in Rio de Janeiro].
PURPOSE To evaluate retrospectively stent implantation (SI) in patients with coronary artery disease (CAD) performed in 7 hospitals in Rio de Janeiro. METHODS From June/94 to December/96 2,220 procedures were performed among which we analyzed 783 SI in 660 (29.7%) patients using coronary angiography without digital subtraction. Several types of stents were used: Palmaz-Schatz (40.9%), Giantur...
متن کاملImmediate outcomes of eptifibatide therapy during intracoronary stent implantation
BACKGROUND The objective of the present study was to assess the major immediate outcomes of eptifibatide therapy during intracoronary stent implantation. MATERIALS AND METHODS In an interventional study, patients undergoing percutaneous coronary intervention (PCI) were randomized into either the eptifibatide (n = 100) or the control (n = 107) group. In each group, demographic and clinical cha...
متن کاملPercutaneous implantation of a new intracoronary stent in pigs.
Sixty-two self-expanding parallel wire stainless steel stents were implanted in normal coronary arteries of 31 young pigs using a newly developed delivery system. In 57 of 62 procedures, the percutaneous coronary implant of the stent was successful; five stents were released in side branches. Implants remained in place for a few hours to 6 months. In spite of correct sizing, two stents migrated...
متن کاملCoronary stent implantation technique: prolonged inflation time maximizes stent expansion.
OBJECTIVES To determine whether longer periods of stent balloon inflation result in greater minimal luminal diameter (MLD) as measured by quantitative coronary analysis (QCA), and to determine whether measured size correlated with that predicted by pressure-diameter nomograms. METHODS Seventy-four stents were implanted in 52 patients. Stent acquisitions at a steady inflation pressure were tak...
